Spacewalkers Begin Work to Upgrade Power Systems

Two NASA astronauts switched their spacesuits to battery power this morning at 6:35 a.m. EST Expedition 61 Flight Engineers Christina Koch and Jessica Meir are venturing out into the vacuum of space for about six-and-a-half hours to finish replacing nickel-hydrogen batteries with new lithium-ion batteries that store and distribute power generated by the station’s solar arrays on the station’s port truss. The lithium-ion batteries provide an improved power capacity for operations with a lighter mass and a smaller volume than the nickel-hydrogen batteries.

Hubble-Konstante: Diskrepanz der Messwerte bestätigt

Die Frage nach dem Wert der Hubble-Konstanten schien schon geklärt zu sein, bis der ESA-Satellit Planck aus der kosmischen Hintergrundstrahlung einen deutlich niedrigeren Wert bestimmte, als mit lokalen Verfahren gemessen wurde. Eine jetzt vorgestellte Analyse neuer Beobachtungen bestätigt nun diese Diskrepanz. Könnte sie ein Hinweis auf eine neue Physik sein?
